How much are a set of Headliner Percussion Bongo's worth?

As the title states. How much are an average set of Headliner Bongo's worth? I know this is probably the wrong section, but you all know me here, and I would appreciate an honest answer, if I were to post this in waffle or somewhere else god knows the response I'd get!

Anyway, I have this set of Bongo's made by Headliner, had them for around 10 years now, nothing wrong with them, almost immaculate condition. skins still intact, not ripped or worn. They are a pine wood effect, with black and chrome seals and structures. I cant find the same model anywhere online which is why I'm here!

They look identical to these, but with completely different logo's and badges.

Edit - I'm looking at selling them as I don't really use them at all. They are just sitting in a store cupboard collecting dust and taking up space. Figured I'd use the money made to put toward something more useful.

ive got a pair of those. after ten years the skins will prob be fucked unless you oiled them and slackened them off while not being used. you'll prob get up to £40 i recon. you could mug someone off on ebay say you've only had them a week?
